In certain exemplary embodiments of the present disclosure, after the control device is connected to the first electronic device through the USB interface, an unknown virtual function device is displayed on the control device, and a message box is popped up on the first electronic device, such that a user may select the functions thereof in the message box according to needs. In certain exemplary embodiments, the selected functions cannot occupy the same mobile phone resource. For example, the media transfer protocol (MTP) and the picture transfer protocol (PTP) cannot be selected at the same time since MTP and PTP occupy the same storage resource of the first electronic device, and thus operations cannot be performed thereon simultaneously.

After selection of the functions, the control device performs the enumeration process. In other words, that is, the control device performs the process to send a command of obtaining the descriptors, and thereby obtaining the descriptors corresponding to the functions selected by the user.

In one exemplary embodiment of the present disclosure, with respect to one of the functions, a corresponding descriptor may include some or all of the following information: a device descriptor, a configuration descriptor, an interface descriptor and an endpoint descriptor.

After obtaining the descriptors corresponding to the functions selected by the user, the descriptor information corresponding to the functions will be matched with corresponding function driver files of the control device. For example, if MTP and Android Development Bridge (ADB) are selected, the descriptor information of the MTP function is matched with an MTP driver file of the control device, and the descriptor information of the ADB function is matched with an ADB driver file of the control device. Specifically, the matching process may be described using the ADB function as an example. After the descriptor information of the ADB function is obtained, the control device selects configuration information corresponding to the function in an ADB driver file, and matches the selected configuration information with the obtained descriptor information. If the matching is successful, one of a plurality of unknown virtual function devices displayed on the control device is selected, and the selected unknown virtual function device is configured according to the selected configuration information through a set_configuration request, such that the configured virtual function device is taken as a virtual function device corresponding to execution of the function.

After a corresponding operating command is received, the operating command is delivered to a corresponding virtual drive device through a corresponding driver interface, thereby implementing the operation on the mobile phone, for example, a delete operation is performed on a video of the first electronic device through the MTP function, and when the control device receives an operating command of deleting a related video, the command is delivered to an MTP driver interface and then is delivered to an MTP device through the MTP driver interface, thereby implementing the operation of deleting a video from the first electronic device. In one exemplary embodiment of the present disclosure, while the first electronic device is operated through the MTP function, the first electronic device can also be operated by using the ADB function or another function that does not occupy the same resource of the first electronic device with the MTP function.

In one exemplary embodiment of the present disclosure, after detecting the USB interface being connected to the first electronic device, the control device sends a command of obtaining the descriptors to the first electronic device through the USB interface. Further, after sending the command of obtaining the descriptors to the first electronic device, the control device receives the descriptors corresponding to at least one of the functions of the first electronic device through the USB interface.

In certain exemplary embodiments of the present disclosure, the command of obtaining the descriptors may be an existing command of getting one descriptor. However, in certain exemplary embodiments, there may be multiple descriptors, and the command may also be a new command.

For example, the control device may send a get_device_descriptor standard request to the first electronic device through an address 0 in order to obtain a device descriptor. Then the control device may send a get_configuration request to the first electronic device in order to obtain a configuration descriptor.

After the control device is connected to the first electronic device through the USB interface, a message box may pop up on the first electronic device to require the user to select a function mode thereof. If the user selects a charging mode, it indicates that the user only requires charging of the first electronic device without the need to operate the first electronic device. In this case, the control device does not perform the enumeration process again. Alternatively, the control device needs to perform the enumeration process.

Therefore, the control device, after detecting the USB interface being connected to the first electronic device, may determine whether the first electronic device is in a non-charging mode. If the control device determines that the first electronic device is in the non-charging mode, the control device receives the descriptors corresponding to at least one of the functions of the first electronic device through the USB interface. In other words, when a function such as MTP, ADB or PTP is selected through the message box popped up at the first electronic device, such as a mobile phone, which is in the non-charging mode, the control device needs to perform the enumeration process. Thus, it is necessary to determine the selection mode of the first electronic device prior to the enumeration process.

In one exemplary embodiment of the present disclosure, the method further includes: after the control device detects the USB interface being connected to the first electronic device, if the control device determines that the first electronic device is in a charging mode according to the mode information received from the first electronic device, the control device skips the operation of receiving the descriptors corresponding to the functions of the first electronic device through the USB interface to directly perform a charging operation on the first electronic device.

If a charging mode is selected, the PC will directly charge the mobile phone, and skip the process that the control device receives the descriptors corresponding to the functions of the first electronic device through the USB interface, the subsequent processes of matching the descriptors corresponding to the functions with the driver files corresponding to the functions and determining a virtual function device, and the process of operating one or more functions of the first electronic device. Thus, the purpose of allowing the user to perform a charging operation on the mobile phone through the PC without installing a driver thereon may be achieved.

FIG. 2 shows a flowchart of a method for setting a USB interface according to one exemplary embodiment of the present disclosure. As shown in FIG. 2, the method includes:

Operation 200: A first electronic device detects a connection with a control device through a USB interface.

Operation 201: The first electronic device receives a command of obtaining descriptors sent by the control device.

Operation 202: After receiving the command of obtaining descriptors sent by the control device, the first electronic device displays a plurality of functions each corresponding to one virtual port of a plurality of virtual ports.

Operation 203: The first electronic device generates each of the corresponding descriptors according to a corresponding USB driver to each of the functions selected by a user.

Operation 204: The first electronic device sends the generated descriptors to the control device through the USB interface.

In certain exemplary embodiments of the present disclosure, in a USB device, a virtual port interface is taken as a unit thereof. Thus, different functions correspond to different interfaces, where the different functions cannot occupy the same resource of a mobile phone. Thus, an operation of selecting at least one of functions in a message bar of the mobile phone may be implemented. For example, MTP may correspond to interface 0, and ADB may correspond to interface 1, such that the user may select both MTP and ADB functions at the same time or just one of them.

In one exemplary embodiment of the present disclosure, after the first electronic device detects the connection with the control device through the USB interface, the method further includes: the first electronic device determines corresponding mode information according to a mode selected by a user, and sends the determined mode information to the control device, where the mode information is configured to indicate whether the first electronic device is in a non-charging mode.

FIG. 3 shows a flowchart of a method for operating a first electronic device according to one exemplary embodiment of the present disclosure. As shown in FIG. 3, the method includes:

Operation 300: In a USB device, configuring different functions, which do not occupy the same resource of the first electronic device, to correspond to different interfaces.

Operation 301: Connecting the first electronic device to a control device through a USB interface, pop up a message bar on the first electronic device, and a user makes a selection according to requirements.

Operation 302: Determining whether a charging mode is selected in the message bar of the first electronic device. If so, the control device performs Operation 303; otherwise, the control device performs Operation 304.

Operation 303: The control device skips the enumeration process and directly charges the first electronic device; and the process ends.

Operation 304: If MTP and ADB functions are selected in the message bar of the first electronic device, the control device performs the enumeration process to obtain descriptors corresponding to MTP and ADB.

Operation 305: Matching the descriptor of the MTP and the descriptor of the ADB respectively with a corresponding MTP driver file and a corresponding ADB driver file on the control device.

Operation 306: If the matching is successful, after the control device is connected to the first electronic device through the USB interface, determining unknown devices displayed on the control device to be an MTP device and an ADB device.

Operation 307: The control device, after receiving a corresponding operating command, sends the operating command to a corresponding driver device through a corresponding driver interface, thereby implementing an operation on a mobile phone.

One exemplary embodiment of the present disclosure further provides an apparatus for operating a first electronic device. As the method corresponding to the apparatus for operating the first electronic device is the method for operating the first electronic device, the apparatus may be implemented with reference to the method as described above, and is thus not elaborated herein.

Correspondingly, the memory may also include a memory controller to control access to the memory by the processor and the input device.

The input device may be used for receiving input digital or character information, and generating input signals that may be related to user settings and function control, such as a keyboard input signal, a mouse input signal, a joystick input signal, an optic input signal, or a trackball input signal. Specifically, the input device may include a touch-sensitive surface, and other input devices. The touch-sensitive surface, also referred to as a touch screen or a touchpad, may collect touch operations performed by a user on or near the touch-sensitive surface (for example, operations performed on or near the touch-sensitive surface by a user using any proper object or accessory, such as a finger, a stylus, and the like), and drive a corresponding connected apparatus according to a preset program. Optionally, the touch-sensitive surface may include two parts, including a touch detection apparatus and a touch controller. The touch detection apparatus is configured to detect a location of a touch performed by a user, to generate a signal caused by the touch operation, and to transmit the signal to the touch controller. The touch controller is configured to receive touch information in the signal from the touch detection apparatus, to convert the touch information into a touch point coordinate, and to send the touch point coordinate to the processor. The touch controller may also receive and execute a command sent by the processor. In addition, the touch-sensitive surface may be implemented in multiple types, such as a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type. In addition to the touch-sensitive surface, the input device may further include other input devices. Specifically, the other input devices may include, without being not limited to, one or more of a physical keyboard, a function key (for example, a volume control key, an on/off key, and the like), a trackball, a mouse, and a joystick.

The display device may be used for displaying information input by the user or information provided for the user, and various graphic user interfaces of the electronic device 6000.

Further, the touch-sensitive surface may cover the display panel, and after detecting a touch operation on or near the touch-sensitive surface, the touch-sensitive surface may send a touch event to the processor so that the processor determines the type of the touch event. Then, the processor provides a corresponding display output on the display panel according to the type of the touch event. In certain exemplary embodiments, the touch-sensitive surface and the display panel are configured to respectively implement the input and output functions as two independent components. Alternatively, in certain exemplary embodiments, the touch-sensitive surface and the display panel may be integrated as one component to implement the input and output functions.

On the other hand, the microphone converts a collected sound signal into an electrical signal, and the audio frequency circuit receives and converts the electrical signal into audio data. After the audio data is sent to and processed by the processor, the processed audio data is sent by the radio frequency circuit to, for example, another apparatus, or is output to the memory for further processing. The audio frequency circuit may further include an earplug jack to provide communications between a peripheral earphone and the electronic device 6000.
